HEATER FOR ATTACHMENT TO OIL OR GAS BURNERS.

SPECIFICATION forming part of Letters Patent No. 569,377, dated October 13, 1896.

Application filed ay 27, 1895, Serial No. 550,775. (No model.)

To (all whom it may concern:

Be it known that I, HEEvEY I-I. HALLETT, a citizen of the United States, residing at Rock- 1and,in the county of Plymouth and State of lllassachusettsdiave invented certain new and useful Improvements in IIeaters for Attachment to Oil or Gas Burners; andl do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to figures of reference marked thereon, which form a part of this specification.

This invention relates to heaters especially adapted for either the nursery or for general household purposes and may be employed on oil or gas burners.

The object of my invention is to enable light cooking to be performed without the aid of a stove; and my invention is further embodied in the construction of the heater, which is designed to fit any size or shape of chimney or applicable to gas-burners either with or without a globe.

The drawings represent, in Figure 1, a side elevation of a heater embodying my invention applied to the chimney of an oil-burner. Fig. 2 is a similar view of the heater applied to the globe of a gas-burner. Fig. 3 is an elevation of the heater attached to a gas-burner withouta globe. Fig. trepresents the heater, enlarged, with a radiating cap. Fig. 5 is a sectional view in part, showing a support removably' attached. Fig. 6 is an enlarged section of the foot of the support as in Fig. 3. Fig. 7 is a plan.

In said drawings I have shown a heater 2 as applied to the chimney of an oil-burner. This heater is preferably a circular plate or disk 4:, of some thin sheet metal, which is centrally apertured for the direct radiation of heat, if it is desired. In order to secure said heater in place and to render its application universal or to any size or shape of chimney, I have attached pendent legs or supports 5, preferably three in number, while the lower extremity is formed with a bent portion or foot 6. This foot comprises a series of flexures, whereby the folds 7 7 of the material forming the support are in parallelism with each other, but non-contiguous and approximate in their position with the surface of the chimney at the top. By reference to Fig. 1 it will be seen that these supports may be reversible about the holding device and thus enable the heater to be applied either to a chimney with an outwardly-flaring top or to a very large chimney of the pattern shown in Fig. 1. By this peculiar construction of the foot of the support a certain degree of flexibility is imparted to it, and in this way the heater is adapted to fit chimneys of different sizes and shapes. Moreover, this form of support not only firmly c-lasps the chimney or globe, but it is held above and is not in contact with the top; consequently when in position does not affect the draft.

The above-described construction is peculiarly fitted for use on the chimneys for oilburners, but to enable the heater to be equally serviceable with gas-burners I have slightly modified the construction by increasing the length of the leg, owing to the greater degree of heat produced by the combustion of the gas. Furthermore, in addition to the foot under the previous construction mentioned, I have pierced the lowermost outer portion at 9, in order to receive the holdingscrews 10, with which the globe-holder 12 is equipped, in order to maintain the globe 13 in place. The engagement of the supports with the holding-screws occurs only when the globe is removed and the relative positions of the parts are as shown in Figs. 3 and 7 of the drawings. On the other hand, presuming that the globe remains in place, then the flexed portion comprising the foot is caused to engage the rim of the globe, as illustrated in Fig. 2. Under these conditions the holes 9 are not employed, but only the flexed part of the foot.

In some instances it is convenient to be able to pack the heater snugly together, in order to have it when traveling. To this end, in lieu of riveting or permanently attaching the supports to the plate 4:, screw-threaded bolts 14, with nuts 15, are supplied, or, as shown in Fig. 2, the upper ends may be folded and held to the plate by friction produced by the inherent spring of the metal. In this way the supports are easily detached and reversed and as easily affixed when it is so desired.

In case the heater is to be employed as a heater proper, after the manner of a radiator, to warm the air in a room, a supplementary radiating-plate 16, of larger dimensions, is superposed. This cap is likewise provided with supports which rest upon the lower disk and uphold the radiating-plate a short distance thereabove, being removably attached.

I do not desire to be confined to the exact shape of the disks, since, in lieu of being circnlar, they may be polygonal, while the supports may be varied in number and may be tubular or otherwise in cross-section to make them, if it is so desired, more ornamental or to give them greater stiffness to uphold any article which may be placed upon the heater.

IVhat I claim is-- In combination with a metallic plate, two or more pendent supports detachably aifixed thereto, a plurality of folds at the lower extremity of said supports to form a flexible foot, and a perforation likewise in the end of each foot, whereby the plate may be mounted upon a chimney, a globe, or a globe-holder, as set forth and explained.

In testimony whereof I affix my signature in presence of two witnesses.
